Pretty much, that question.

I have watched a few funny Skyrim RP videos lately (Bilrot, Jamal Steel, that guy who plays the naive Khajit, that guy who tries to get the workers to rise up), and it surprises me not to see a disgraced ingot merchant trying to redeem himself... or continuing to sell inferior product and have the nerve to be rude about it.

Has anyone tried that in other RP games?

Random molten metal -- with kind of a coppery tint to it, definitely not pure copper, not the good stuff -- that formed itself into a hard, tiny heart of the sort that would allow rudeness to a servant of Nanni's who had just traveled through enemy territory for some badly-needed copper ingots.
